Through new experiments with magnetic materials, physicists in Austria and Hong Kong have overturned a simple law of friction that has held for over 300 years. Led by Clemens Bechinger at the University of Innsbruck, the team’s discovery shows how internal collective dynamics in these materials can cause friction to peak at a certain applied, load before dropping sharply. The effect could prove especially promising in applications where friction needs to be precisely controlled.
